Officer Bryan Crenshaw was behind the wheel of his squad car January 22, when he struck and killed 43-year-old Beverly Kirk in the 9900 block of Bruton Road.

Crenshaw, who was responding to a disturbance call, did not have his lights and siren on when Kirk stepped into traffic and was struck. She died at the scene.

“Through the accident reconstruction process, it is estimated that Officer Crenshaw was traveling from 41 to 43 mph at the time of impact,” said Lt. James “Scott” Walton, a Dallas Police spokesman. “The posted speed limit was 35 mph. The Internal Affairs Division will be conducting an administrative investigation into Officer Crenshaw’s speed at the time of the accident.”

There was no police dash camera on Crenshaw’s squad car, Walton said, and the Medical Examiner’s toxicology tests indicated Ms. Kirk had a blood alcohol content of 0.25 and was positive for the presence of cocaine.

“This was a tragic accident and the Dallas Police Department wishes to convey its condolences to all members of Ms. Kirk’s family on the loss of their loved one,” Walton said.
